I made this using, my custom, bin2bin boot loader, ready made of the dde bor game.. Double dragon Extreme

https://mega.nz/#!qzh0wIYJ!MkeNSaOrKp1w ... eYEcpSlxH0

I use a very custom kos Compiler setting's .. Sometime's you need my boot loader..
So try this if it did not work, on your real dreamcast.. tested by Ivan GR thank you it's working now

Lo siento mi amigo, esta versión beta sigue con el mismo problema para mis juegos. Pero es una buena oportunidad de comenzar desde cero y actualizar mis juegos a 640x480 @ 16bits para darle a los usuarios de DC juegos de alta resolucion...

Hi ripfire,

Code: Select all

libpng warning: Application built with libpng-1.2.8 but running with 1.6.19

libpng warning: Application built with libpng-1.2.8 but running with 1.6.19

I ran your game's thru the debug log. it is asking for PNG1.2.8 i was using PNG1.6.19 new one.. It say cant do 8x8 palette BUILT this version with PNG1.2.8 not PNG1.6.19 it was making it crash.. This may fix it.. worth a try It's the only thing on the debug log that was coming up when loading your games.

Here is a version built with PNG1.2.8 like it ask's
https://drive.google.com/open?id=1PgfER ... SDYQd3UZTL

I played it on nulldc thru a few level's I might have a older version of your pak file.. I'm trying to fix the problem.. It will take beta testing and debug info. I have many version of the png.lib and header's

============================================================================================================================
Cache enable

Beta5 cache enabled ,Png 1.6.19 Lowest memory use.. Bin size 992kb

I had the wrong header file's this one is correct, try it as well. This has the cache system back to normal.. If it work's on any other version it should on this..

Running on cache enable your game run's out of memory

Hi,
Since , downporting change's from the new openbor source code is winning the poll i have started with this..
I have down ported SDL correct 320x240 8,16,32bit SDL rending code from openbor version 6xxxx to openbor dreamcast 4111

check this topic for info
https://www.dreamcast-talk.com/forum/vi ... 52&t=11856

Old version SDL rending for dreamcast Beta5 and official openbordc4111

New Version SDL rending for dreamcast Beta 6 downported from version 6xxx

We all so , now have full transparencies,shadow and correct colour's for 16bit palette and 32bit palette, 320x240 is fast 640x480 very slow
also , in the video.txt you can put custom res like 640x360 etc In video.txt video 640x360 dont have to use, video 1 , 2 ,3 etc Title's and menu's and scene will not scale.. But gameplay should I have ported stretching..

This is my thinking it out here.. the pc menu selector is now working

Well i have been holding off ,for a release because i was working on porting the pc menu selector, to dreamcast, i have done that it boots, finds the pak file's displays, them, but cant find it on the cd.. error's out on level.txt.. I dont know why right now.. I think beta6 will have to have no menu selector for now.. I really wanted! to get this working for you guys... I have hit a error i cant track down today, here is the progress....

Menu ported to the dc port.. Notice finding all pak file's

Example of it showing the previews

At the moment i will have to take a break . Menu does work but it still only boots the one game named bor.pak it does show all the other games and even show's previews while selecting them , but it does not load them Only bor.pak . Beta6 without the menu selector will be out later tonight , with full sourcecode..

Well scatch that i now have the whole thing working and the openbor menu selector

Fixed my errors

All i can say is, it helped me using this post as a dev log

this is a great place

You are a fucking machine brother! You are doing so much for the community it is amazing! That PC menu will come in handy for sure! Maybe we can have super large 4GB .cdi images of game compilations so we can load them up on our optical drive emulators. A 700mb cdr is no longer a limitation for us.
